Definitions

• the present invention relates to a housing for shielding electromagnetic interference.
• the device consists of a flexible, adaptable in shape to the device to be tested, for electromagnetic interference impenetrable, closed on all sides shell of a conductive material, which is preferably a metallized textile fabric. In this case, the closed on all sides shell on a zipper or a Velcro closure.
• a two-part housing is common, the first housing part and the second housing part are fixed with a large number of screw connections to each other.
• the disadvantage of this is the complexity of the variety of screw, which are mechanically stable, but expensive to manufacture and install.
• Another disadvantage is that such a housing is not absolutely electromagnetically sealed, since there are slots between the individual screw, which are permeable to the electromagnetic radiation.
• the invention is therefore based on the object zuffe a housing, the housing parts are non-destructive and easily solvable, the connection of the housing parts is electromagnetically absolutely tight.
• Claim 1 describes a housing for shielding electromagnetic interference.
• the housing according to the invention consists of a first housing part with a first Velcro fastener element and a second housing part with a second Velcro fastener element each of conductive material, wherein a slot between the first housing part and the second housing part by means of a made of conductive material third Velcro closure element is electromagnetically sealed.
• An advantage of the housing according to the invention is that, when the two housing parts are placed on top of each other, the slot formed by manufacturing tolerances is electromagnetically sealed between the two housing parts, so that within the invention
• both the material of the first and second housing part and the hook and loop fastener elements may be made of metal, so that the housing according to the invention is electromagnetically sealed.
• An alternative advantageous development of the housing according to the invention is that the Velcro elements are made of conductive plastic.
• the two housing parts can be easily and non-destructively detached from each other.
• FIG. 1 shows a section through an inventive housing with three Velcro elements.
• the housing 1 shows a section through an inventive housing 1 with three hook-and-loop fastener elements 3, 5, 7.
• the housing 1 according to the invention for shielding electromagnetic interference consists of a first housing part 2 with a first hook-and-loop fastener element 3 and a second housing part 4 with a second hook-and-loop fastener element 5
• First and second hook-and-loop fastener elements 3, 5 are each made of conductive material, in particular of metal or of an electrically conductive plastic. Due to manufacturing tolerances, a slit 6 is formed when the two housing parts 2, 4 are stacked on one another, which slot is permeable to electromagnetic radiation. This slot 6 is electromagnetically sealed by means of a third made of conductive material Velcro element 7, whereby a good shielding of the housing interior 11 is ensured with respect to an environment of the housing 1 according to the invention.
• the conductive material of the three hook and loop fastener elements 3, 5, 7 is either a metal or a conductive plastic.
• Side walls 8, 9 of the first and second housing parts 2, 4 may each have a metallic layer with an enlarged surface corresponding to an adhesive layer of a hook and loop fastener element 3, 5, wherein the metallic layer with the increased surface area on the side walls 8, 9 of the first and second second housing part 2, 4 may be vapor-deposited.
• the third hook-and-loop fastener element 7 is provided as a connection of the first hook-and-loop fastener element 3 to the second hook-and-loop fastener element 5 and surrounds the contact point 12 between the first and the second Housing part 2, 4.
• the third hook and loop fastener element 7 is therefore designed as a counter element complementary to the first and second hook and loop fastener element 3, 5. It has z. B. hooks when the first and second hook and loop fastener element has a felt and vice versa.
• a circumferential groove 10 is provided in the embodiment.
• the housing 1 according to the invention is closed by placing the first housing part 2 on the second housing part 4.
• the side wall 8, 9 of the first and second housing part 3, 4 has on its upper side in the exemplary embodiment in each case a circumferential recess 13, 14, wherein these
• Recesses 13, 14 are complementary to each other. If the first housing part 2 on the second
• Housing part 4 placed so a nose 16 of the second housing part 4 fits into the recess 13 of the first
• a Velcro fastener element 3, 5 is inserted, wherein the width of the hook and loop fastener element 3, 5 corresponds to the width of the groove 10 and is thus clamped in this.
• the clamping closure elements 3, 5 can be glued, clamped, inserted or welded to the circumferential groove 10 of the first and second housing part 2, 4.
• the third hook-and-loop fastener element 7 is placed over the hook-and-loop fasteners 3, 5 glued, clamped or welded into the grooves 10 such that a slot 6 is electromagnetically sealed at the contact point 12 between the first and the second housing part 2, 4, wherein the hook-and-loop fastener element 3, 5, 7 is preferably a circumferential hook-and-loop fastener tape.
• the invention is not limited to the illustrated embodiment or the described embodiments and may e.g. Also used to connect two housing simultaneously stable and reversible or non-destructive without much effort.
